Neuroradiology Physician: how many are there, and how many are in private practice?

National totals

What this specialty covers

A radiologist who diagnoses and treats diseases utilizing imaging procedures as they relate to the brain, spine and spinal cord, head, neck and organs of special sense in adults and children.

Reading the sole-proprietor share

For this specialty, 293 of 2,198 active records, or 13.3%, are flagged as sole proprietors. That field is self-reported in NPPES and is an imperfect proxy for private practice because it does not by itself show employment arrangement, practice independence, ownership, or whether a physician works in a group.

By state

New NPI registrations by year

Counts reflect the year each NPI was first issued, among records still active today. The final year is partial: this data covers through 2026-01-11.

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• The count is limited to active NPI records with this taxonomy as the primary classification and is not a census of physicians or imaging practices.
• State and enumeration-year counts may reflect record maintenance, taxonomy selection, or NPI issuance timing, so they should not be used alone to infer workforce growth, location, or causation.
• Providers are counted once, by their primary taxonomy code only.
